TAR-LAID BUILDING MATERIAL.

Application filed April 10, 1926. Serial No. 101,049.

This invention relatesto tar laid building material and has special reference to blocks, bricks, slabs, tiles and other building material made from concrete or thelike.

My invention aims to provide slabs or brick-like til'esthat may be easily and quickly stances a connection may be established by metallic inserts which may also be tarred to provide an air tight. connection between adjacent slabs or til-es. In other instances the slabs or tiles are prepared for the tar connection. In the grooves of a slab or tile may be placed a strip of tar which may be sub jected to heat, by a blow torch or other he ating' instrumentality to soften the tar sothat the tongue or connecting part of an adjacent slab or tile may be placed in the melted tar whereby the tar will seal the tongue and groove connection. \Vith the slabs or tiles provided with the tar or sealing materialthe slabs or tiles are prepared for installation and practically as fast as a workman may manipj ula-te a blow torch, the slabs or tiles may be placed in superposed relation against a siding or inner wall. At suitable intervals wall fasteners may be used to anchor the slabs or tiles, and there is no danger of the slabs or tiles being broken or injured by such fasteners as I employ for anchoring the composite wall.

My invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing wherein Figure 1 is a front elevation of a portion of an outer wall composed of slabs or tiles in accordance with this invention;

Figs. 7, 8 and 9 are detail views, on a similar scale, of a tongue and groove tile, and

Fig. 10 is a vertical sectional view of a portion of a wall formed of tiles such as shown in Figs. to 9. inclusive. i

Reference Will first be had to Figs. lito 6 inclusive showing a slab or block 1 made from concrete or other cementitious materialand the slab is comparatively flat and oblong in elevation. In the making of-this slab a metal horde: tram a2 is mounted therein, said frame forming a skeleton reinforcin-gmember for the slab anda'lfording meansof'connecting The metallic frame comprises a longitudinal tonguebar 3', vertical groovebars or channels 5 and a longitudinal groove baror channel 4. The ends of these bars are spot welded or otherwise connected together with the end bars 5 in substantially the same plane. This isalso true of the longitudinal bars 3 and l and the frame is lo cated in the slab 1 so that the groove or chan- "nel bars 4 and 5 are substantially embedded therein, while the tongue bar 3 protrudes from the slab and-is adapted to extend into fori'ning an inner wall. The ofiset end 7 of 7 Since the fastening. member is tar or other this form of metal reinforced cementitiou's slab, reference will be had to Figs. 7 to 9 inclusive showing a slab 12 devoid of any metallic reinforcement. The slab 12 may be rectangular in elevation with tongues 13 on two of its edges andgrooves 14; in the other edges of the slab, so that the slabs may be laid in superposed staggered relation with tongue and groove connections between the slabs. To secure these slabs to the inner wall, each slab has an angularly disposed nail opening 15 into whicha nail may be driven to anchor each slab relative to the inner wall. In laying either form of slab I find it advantageous to seal the tongue and groove connections wherever possible to insure a tight connection and exclude the elements. I find that tar may be advantageously used as a sealing material, therefore I lay a strip or head of tar in each groove of a slab. Melted or semi-liquid tar is poured in the groove to solidify therein and become an integral part of the slab, so that the tar cannot become accidentally displaced during shipment. When the slabs are ready to be laid, a blow torch or other heating instrumentality is moved along the inlaid tar to melt or place it in a semi-fluid condition that will permit of a tongue either entering the tar or spreading the tar over the wall of the groove. When the tar solidifies there is a positive connection between tongue and groove slabs 12 as shown in Fig. 10, or tongue and groove slabs 1, as shown in Fig. 4.

As shown in Figs. 4 and 5 the metallic lined grooves of the slabs or blocks may have malleable sealing material therein and this is particularly true in connection with the vertical groove members 5 so that the fastening members 6 will be sealed between the confronting groove bars. Such a quantity of tar may be used in each groove bar that it will be displaced by the fastening and form a bond between the confronting ends of the slabs or blocks.

From the foregoing it will be observed that there is a method involved in my invention, which method consists in placing sealing material in grooved building material to solidify therein; then welding the solidified sealing material to place in a fluid or semifluid condition, and then placing the tongue building material on the groove building material with the tongues in the grooves so that the sealing material when again solidified will seal the tongue and groove building ma terial. The method is carriedinto effect by using specially prepared building material and a tar inlaid slab or block constitutes an article of manufacture, with or without the metallic reinforcement.

It is thought that the utility of my invention will be apparent without further description, and while in the drawing there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is:

1. A method of laying tongue and groove building slabs having in the grooves thereof a fusible material which is hard at ordinary temperatures, consisting in melt-ing said inaterial and inserting therein the tongues of adjacent slabs. V

2. A building slab having tongues at certain edges and grooves at other edges thereof, said grooves containing a fusible material which is hard at ordinary temperatures.

8. A slab having tongues inserted in certain edges and channel members in other edges thereof, said channel members containing a fusible material which is hard at ordinary temperatures. i

In testimony whereof I affix my signature.
